【摘要】:基礎(chǔ)隔震技術(shù)近幾十年迅速發(fā)展的結(jié)構(gòu)控制技術(shù),基于此技術(shù)的建筑具有十分優(yōu)良的抗震性能,其應(yīng)用也越來(lái)越廣泛;谛阅艿目拐鹪O(shè)計(jì)是近20年提出的新型結(jié)構(gòu)抗震設(shè)計(jì)方法,提高了生命及財(cái)產(chǎn)安全的保障程度,成為抗震設(shè)計(jì)方法的發(fā)展趨勢(shì);A(chǔ)隔震結(jié)構(gòu)基于性能的抗震設(shè)計(jì)正是將基于性能設(shè)計(jì)思想應(yīng)用于基礎(chǔ)隔震結(jié)構(gòu)的一種設(shè)計(jì)理論。許多學(xué)者針對(duì)非隔震結(jié)構(gòu)性能做了一系列研究,性能指標(biāo)多取為位移、位移角、能量等,對(duì)于基礎(chǔ)隔震結(jié)構(gòu)相應(yīng)研究很少也不全面。本文針對(duì)基礎(chǔ)隔震建筑,提出了一套設(shè)防水準(zhǔn)與性能目標(biāo),給出了性能指標(biāo)的量化參數(shù)及量化值,具體內(nèi)容如下:一、根據(jù)基礎(chǔ)隔震建筑的特點(diǎn)及應(yīng)用范圍,考慮使用功能、社會(huì)功能,以設(shè)計(jì)基準(zhǔn)期為基礎(chǔ)將基礎(chǔ)隔震建筑按重要性分為甲、乙、丙三類,設(shè)計(jì)基準(zhǔn)期分別為200年、100年、50年;二、提出了基礎(chǔ)隔震建筑的設(shè)防水準(zhǔn)表達(dá)式,并進(jìn)行了設(shè)防水準(zhǔn)的劃分,4個(gè)水準(zhǔn)在設(shè)計(jì)基準(zhǔn)期內(nèi)超越概率分別為63%、10%、5%、2%;三、將基礎(chǔ)隔震結(jié)構(gòu)性能水平設(shè)為四個(gè):充分運(yùn)行、可以使用、生命安全、接近倒塌,設(shè)防目標(biāo)取為常遇地震充分運(yùn)行,偶遇地震可以使用,罕遇地震保證生命安全,極罕遇地震防止倒塌;四、綜合分析得到了基礎(chǔ)隔震結(jié)構(gòu)性能水平的隔震層位移、層間位移角、樓層加速度三個(gè)性能化指標(biāo),并從理論上給出了隔震層位移與層間位移角量化值,樓層加速度指標(biāo)則是通過(guò)理論與振動(dòng)臺(tái)試驗(yàn)分析得出。
[Abstract]:The structure control technology based on the foundation isolation technology has developed rapidly in recent decades. The building based on this technology has excellent seismic performance and its application is more and more extensive. Performance-based seismic design is a new seismic design method for structures proposed in recent 20 years. It improves the security of life and property and becomes the development trend of aseismic design methods. The performance-based seismic design of base-isolated structures is a kind of design theory which applies performance-based design to base-isolated structures. Many scholars have done a series of studies on the performance of non-isolated structures. The performance indexes are displacement, displacement angle, energy and so on. This paper puts forward a set of fortification level and performance target for base-isolated building, and gives the quantitative parameters and quantification value of performance index. The specific contents are as follows: first, according to the characteristics and application scope of base-isolated building, the use function is considered. Social function, on the basis of the design reference period, the base-isolated building is divided into three categories according to its importance: a, B, and C, and the design reference period is 200, 100, 50 years respectively. Second, the level expression of foundation isolation building's fortification level is put forward. In addition, the level of fortification is divided into four levels. The transcendence probability of the four levels in the design reference period is 6310 and 50.The third, the performance level of the base-isolated structure is set to four: fully operational, serviceable, safe, close to collapse. The target of fortification should be the full operation of frequent earthquakes, the use of occasional earthquakes, the safety of rare earthquakes, and the prevention of collapse by extremely rare earthquakes. Fourthly, the isolation layer displacement and inter-story displacement angle at the performance level of the foundation isolation structure are obtained by comprehensive analysis. There are three performance indexes of floor acceleration, and the quantized values of the displacement of isolation layer and the displacement between layers are given theoretically, and the index of floor acceleration is obtained by theoretical analysis and shaking table test.
